Will this give me too much fuel on a stock GSR? Or am I getting the same amount of fuel as before because fuel pressure is still stock.

 

I prety sure the High Pressure 255 will give you to much pressure, and you cant turn it down with a stock fpr.

 

Oh ok. I thought having this pump would give me more fueling capacity when i needed it. I'll check my fuel pressure and adjust it.

 

TTT for clarification. Is 42psi fuel pressure delivering the same amount of fuel no matter if you have a 225lph hi flow or OEM fuel pump? Need to know if I'm overfueling and don't know it.

 

I ran my 255 pump before my turbo setup was installed and my fuel pressure was fine and car ran good with the stock regulator.

 

Thanks. Anyone else?

If 225lph were enough to overwhelm the FPR, that would result in higher fuel pressure.
